In 2012, 30 million tons of CO2 are expected to be emitted by the ICT field, but the use of ICT will reduce CO2
emissions by 68 million tons, contributing to CO2 emissions reduction of 38 million tons (Equivalent to 3.0%
of 1990 CO2 emissions in Japan)

Discussions (1/2)
How can a telecom carrier like NTT help, along with society and
businesses, to create a sustainable future ?
zDespite higher electricity consumption due to the spread of ICT devices, ICT
services can reduce overall CO2 emissions by boosting the efficiency of
production processes, reducing demand for transportation and delivery, and
reducing the need for production of physical media such as books, CDs, and
DVDs by enabling the downloading or streaming of content.
zThe use of ICT services in Japan during fiscal 2013 will result in reducing CO2
emissions of 38 million tons, which is equivalent to 3.0% of Japan’s fiscal
1991 CO2 emissions.
zWe believe that new services on NGN, such as high definition TV video
conferencing services and Software as a Service (SaaS)-based applications will
enable environmentally conscious customers to reduce the environmental
impact of their businesses.
(C) 2009 NTT 22
Discussions (2/2)
zIn order to reduce CO2 emissions in the future, it is essential to evolve our
lifestyles through the comprehensive utilization of ICT.
zTo estimate the effectiveness of these behaviors, CO2 reduction by using ICT
will have to be made visible. This requires a common methodology for
evaluating the effects of CO2 emissions reduction on a global basis.
zWe are hoping that the necessary recommendations on the methodology will
be developed as quickly as possible.
Thank you for your attention.
